There’s a few questions you’re asking here. You change your display settings on a plan/elevation in the display settings (right click in a blank space display settings), here you can set the colours/fonts/etc (plus much more, and save the settings) for how things display.

In terms of printing, start with file, Print, Print preview … Here you can set what you want to print (floor plan, elevation), set you scale, set your print mode (hidden lines, texture, work area)… so there are a few things that might get you on the right track.
